Hub spacing question
So, I feel like a bit of a fool that I didn't check this until today. After I built up the rear wheel for my bike, I realized the hub spacing is 120mm OLD, while the frame spacing is 126mm. It fits in there, but I have to flex the stays in just a little bit.
I've heard many times that it's OK to flex the stays to fit a 126mm hub into a frame with 120mm spacing. Is it safe to go in the opposite direction? If not, I just wasted a lot of time.

You can also swap out the hub axle for a longer one, without changing anything else.

kroozer beat me to it!
I'd swap out the axle, re-check your dish, and be good to go.
Cheers,
Chris

Ok guys, that makes sense. I suppose I'll also need a couple spacers?
Anybody got a 126mm axle that would work with a Campy Nuovo Tipo rear hub?

Replace the axle...
1) Be careful to replace the existing spacers, if any, in the proper order on the side of the hub they came off of.
2) Measure the hub and the dropout spacing. You might find the hub is actually 120.5 and the dropout 125.5 or some other combination of slightly weird measurements.
3) Split the difference between two NEW spacers, one each side of the hub, that take up as much of the gap as possible, i.e., if your difference ends up being 5mm, use 2 x 2mm spacers. If it really is 6mm, use 3mm worth of spacers each side. You might have to use 2mm and 1mm, depends on what you can get.
Figure that all out before you order your axle from loosescrews, they have the spacers too.
Easy as cake...dish not affected so long as existing spacers go back on the side they came off of and new spacers are added equally each side of the hub.
